More about DNN reindexing and crawling

Before getting detailed into the error let's discuss reindexing and crawling.

Crawling is the method to automatically discover and scan websites. This is done by analyzing the links from one webpage to another.

Search crawlers do reindex as part of their scheduled tasks. 

However, sometimes reindexing the crawlers will throw tricky errors.

Now, let's see how to fix an error in such a case.

How we do DNN reindexing crawling?

Having a great experience in managing servers, our Dedicated Experts are familiar with DNN errors.

Recently, one of our customers was using DNN 7.2 and his site crawler was not indexing properly.

On checking the schedule history, it showed the below content:

Search: Site Crawler Starting. Content change start time x/xx/xxxx
Tabs Indexed: 0
Modules (Metadata) Indexed: 0
Modules (Content) Indexed: 0
Users Indexed: 0
Total Items Indexed: 0
Indexing Successful

In a detailed analysis, we found that the DNN site used the Lucene search engine.

It is a file-based type of search engine. And, this caused the error.

To resolve this error, we followed the steps below:

1. Firstly, we took the backup of the site.

2. Then, we deleted all the files in the folder C:\Inetpub\vhosts\domain.com\httpdocs\App_Data\Search.

3. We then clicked the button under Admin > Search Admin > Re-Index.

4. Then, Host > Scheduler > Site Crawler to RUN status.
